UPDATE at 4:22 p.m.: Tim Tebow is officially listed as questionable. Still hearing that no decision has been made for Sunday, though.

Despite an ESPN report to the contrary, Rex Ryan said the Jets aren't sure if they'll deactivate Tim Tebow (ribs) this Sunday.

Ryan also said he was unsure if the Jets would make third-string QB Greg McElroy active as a stopgap in case Mark Sanchez gets injured.

"We're looking into it, he's been limited, really very limited and some of the snaps -- he takes a few offensive snaps, but we'll see how he feels. It could be a game-time decision," Ryan said. "Right now we haven't done anything."

Tebow has been limited throughout practice this week and did not throw any passes during the portion available to the media today.
